LCR Impedance Viewer for Picoscope+Keysight+R&S Bode Plot Data (open source)

[RPuccio]

Hi _Wim_,

Sorry for bothering you again, but it seems like I now have a weird issue with the software (haven't used it for a while). I now run Windows 11 and recently reinstalled FRA4PS v0.9.0, PicoSDK x64 v11.1.0.418 and ImpedanceViewer1014. Unfortunately, I now encounter an error while running the software when I click on the Measure > Picoscope button, which reads the following :

"An attempt was made to load a program with an incorrect format
HRESULT Exception : 0x8007000B"

If I click "ok", the setup window opens and I get a crash when starting measurement with the same erreor code and the following exception text. Any idea what I am doing wrong here, by any chance ? Should I raise an issue on Github instead ?

Thank you very much,
Best regards,
Rodolphe

do you have  dot Net v 4.8 installed,  seems some of them are .net related ??   

HRESULT Exception : 0x8007000B"   is dot net related ?

search all dll file names,  it may point you to say some packages needed to be installed ?    like C++ runtimes, VB runtimes or else ...  or even some could be not registered ?

Will have a look at this in the weekend. One question, does FRA4PS run fine on that machine directly using the FRA4PS GUI? (it seems like it is triggered directly from FRA4PS)

[RPuccio]

@Coromonadalix : I ithought I installed the latest version, but now I'm starting to doubt it was the correct file at all. I run Windows 11 24H2 and i can't install .NET4.8 as it detects a newer version is already installed on my machine. I'm running a Windows update on my machine just to see if it helps.

_Wim_ : yes, FRA4PS is working like a charm !

Thank you both for such a fast reply by the way !

Hi RPuccio, just had a check, the impedance viewer app was not made for X64. So you will have to install "FRA4PicoScope_0.8.0_beta.msi" (last X86 version) and also the X86 SDK from picoscope. This should normally fix the issue.

[RPuccio]

Alright, I didn't think at all that would be that simple ! I've installed everything but don't have yet my Picoscope on hand, I'll report when I get it back next Tuesday.

Thank you so much !

I checked on my pc, and this should do the trick. When I made the app, an X64 version FRA4PS did not exist. X86 uses "Stdcall" as the calling convention for non managed code, while X64 typically uses "Cdecl". I am also not sure if some of the dll API changed with the new version, so for now it is best to use "FRA4PicoScope_0.8.0_beta.msi"...

[coromonadalix]

you have this : FRA4PicoScope_64-bit_0.9.0b.msi

from : https://bitbucket.org/hexamer/fra4picoscope/downloads/?tab=downloads&iframe=true&spa=0


does it work ?

EDIT : see next  post

[_Wim_]

No, this is causing issues. This dll is a 64-bit dll, and needs to be called differently from my app (at least using a different calling convention for Pinvoke, could be some other API differences also, have not checked). So for now I propose to only use the 32-bit version, I might make a dedicated X64 version in the future, but I do not think there is much benefit...

[RPuccio]

Confirmed, everything works fine and both FRA4PS and the ImpedanceViewer can coexist without issues. Thank you so much for such a fast reply, you're the best !
